'Some events were not shown in the calendars below because there were too many of them' error in Team Calendars for Confluence
Symptoms
The following error message appears in Team Calendars for Confluence:
Some events were not shown in the calendars below because there were too many of them
Cause
By default, it's 200 events per calendar. Note that this limit applies to all events in one calendar, and not just the events that are displayed on screen.
Resolution
Restrict the amount of events returned by the JQL query to less than 200 by using a time based filter such as: "created >= startOfDay(-60)"
If the query can't be modified, the system property "com.atlassian.confluence.extra.calendar3.display.events.calendar.maxpercalendar" can be configured to allow more events. See Configuring System Properties.
For example, add something like the following to the end of your JAVA_OPTS:
-Dcom.atlassian.confluence.extra.calendar3.display.events.calendar.maxpercalendar=300In the event the above doesn't resolve the issue, you can check Calendars aren't displayed due to invalid Time Zone, and apply its workaround if timezones are invalid.
